Mesa will operate the 30 E175s for Chicago-based United under a long-term capacity agreement. The mainline carrier owns the aircraft.

The E175s operated by SkyWest Airlines will be based at Chicago O’Hare International airport, according to a recent newsletter from United to its employees.

SkyWest will begin flights with the type on the Chicago-Washington National route on 17 May, with flights to Atlanta, Boston Logan, Minneapolis/St. Paul and New York LaGuardia coming online during the next month.

The Utah-based regional carrier has an agreement with United to operate 40 E175s.
